FIELD: agriculture. SUBSTANCE: greenhouse has walls, a roof, vegetation compartments, and optical radiation sources. Racks for growing cucumbers are triangular prisms having cross-bars joined in pairs. The cross-bars form triangular frames. The greenhouse has two groups of optical radiation sources. The first group is located under the racks, and the other group is located also under the racks - those of each vegetation module. The sources in the first group are those with the following optical flow energy distribution: 400-500 nm - 15-25%, 500-600 nm - 35-45%, 600-700 nm - 35-45%. The sources in the second group have the following flow energy distribution: 400-500 nm - 50-20% , 500-600 nm - 10-30%, 600-700 nm - 55-75%. EFFECT: improved growing conditions. 3 dwg
